The Reduction of Group 6–8 Transition Metal Oxides with Hydrogen—From Ore Smelting to Reaction Pathways#

European Journal of Inorganic Chemistry, EarlyView.
As the reduction of transition metal oxides by coal poses a significant climate risk, the use of alternative reducing agents such as hydrogen is becoming increasingly important. This review summarizes the current knowledge of the reduction pathways of transition metal oxides from groups 6 to 8.

Numerical Simulations of Hydraulic Fracturing in Carbonate‐Type Hot Dry Rock Reservoirs Based on the Coupled Thermo‐Hydraulic‐Mechanical‐Damage (THMD) Model

Energy Science &Engineering, EarlyView.
ABSTRACT Hydraulic fracturing technology is widely used in Enhanced Geothermal System (EGS) projects to induce fractures and enhance the permeability of thermal reservoirs. The hydraulic fracturing process of hot dry rock (HDR) is actually a multiphysics coupling process that couples the heat transfer field, seepage field, stress field, and damage ...

Analysis of the Effective Dose to the Public Living Around Korean Nuclear Power Plants After the Monitoring of Carbon‐14 Discharge Was Implemented

Energy Science &Engineering, EarlyView.
ABSTRACT Radioactive effluents discharged by nuclear power plants (NPPs) are classified into two categories: gas and liquid effluents, based on their source and discharge pathways. During the operation of these facilities, both types of effluents are released into the environment.
